Image
Rigid foam insulating sheathing is installed on existing garage ceiling and covered with a new gypsum board fire protection layer installed over the foam.
Image
Image
Seal the drywall to top-plate seams and the lower edge of baffles to the top plate to prevent the air coming from soffit vents from flowing under baffles into insulation.
Image
The attic kneewall and the open floor cavities under kneewall are both sealed and insulated in one step with spray foam insulation
Image
The original corner seam is air-sealed with caulk, then rigid foam is installed on the existing garage ceiling and walls, and finally covered with drywall.
